Japanese Patent Laying-Open No. 2015-10104573 (first page, FIG. 1 etc.)

∙ By using 3D printing, it is possible to easily create objects with complex structures. However, in the conventional technology, the inside of an object produced by 3D printing is all filled with a material such as a resin used for 3D printing, so the amount of resin etc. used for 3D printing increases. As a result, there is a problem that the material cost becomes high. In particular, there is a problem that the material cost is high because the material for 3D printing is a dedicated material and expensive. Further, since the time required for printing becomes long, the time required for printing one object increases, resulting in a problem that the manufacturing cost increases.

Also, if the inside of the object is hollow, depending on the shape of the object to be produced, the type of resin used for printing, etc., it will not be possible to maintain sufficient strength, and it will not be possible to produce a good quality object. There was a problem.

(Embodiment)
FIG. 1 is a perspective view showing an example of a composite object 1 according to the present embodiment (FIG. 1A), and a state before a plurality of parts constituting the second object 20 are attached to the first object 10. It is a figure (FIG.1 (b)) which shows an example.

FIG. 2 is a perspective view (FIG. 2 (a)) seen from above showing an example of a toy block 101 used for constituting the first object 10, and a perspective view seen from below (FIG. 2 (b)). ), A perspective view (FIG. 2 (c)) viewed from above showing an example of a state in which two toy blocks 101 are assembled, and a perspective view (FIG. 2 (d)) viewed from below.

The composite object 1 includes a first object 10 and a second object 20. A composite object is an object composed of a plurality of objects, for example. The plurality of objects constituting the composite object may be objects of the same material or different materials.

The first object 10 is an object having, for example, one or more assembling toy blocks 101 (hereinafter referred to as blocks 101). For example, it is an object assembled with one or more assembled toy blocks 101. The first object 10 may be considered as an object for reinforcing the composite object 1. Even when the number of blocks 101 constituting the first object 10 is one, it may be considered that the first object 10 is assembled by one block. The shape of the first object 10 is not limited as long as it can be assembled by one or more blocks 101. Two or more blocks 101 composing one first object 10 are usually assembled by coupling coupling means 1011 described later. Note that two or more blocks 101 constituting one first object 10 may be coupled by the coupling means 1011 and further adhered by an adhesive or the like.

Each of the one or two or more blocks 101 has one or two or more coupling means 1011 used for coupling with the other one or two or more blocks 101. Each block 101 has, for example, one or more engaging means 1012 that engage with the connecting means 1011, and at least one connecting means 1011 of one block 101 is at least one of the other blocks 101. By engaging with one engaging means 1012, for example, as shown in FIG. 2C or FIG. 2D, one block 101 and another block 101 are coupled. Thus, the block 101 is combined and the first object 10 is assembled. The coupling means 1011 is, for example, a protrusion provided on the block 101 as shown in FIG. The protrusion may have a cylindrical shape or a quadrangular prism shape, and the shape and size thereof are not limited. The engagement means 1012 is, for example, a recess, a groove, a gap, or the like that engages with the projection that is the coupling means 1011 as shown in FIG. The block 101 is usually provided with coupling means 1011 on the upper surface side, and with engagement means 1012 on the bottom surface side.

The material or color of one or more blocks 101 is not limited. The material of the block 101 is, for example, resin. Further, the size of the block 101 does not matter.

The solid shape of the block 101 does not matter. For example, the three-dimensional shape of the block 101 is a rectangular parallelepiped or a cube. The plurality of blocks 101 constituting the first object 10 may be blocks having the same three-dimensional shape, or may be blocks having different three-dimensional shapes. The one or more blocks 101 may be blocks having one or more coupling means 1011 on a plate-like member. For example, such a block 101 can be used as a base or mounting table for the first object 10. The two or more blocks 101 used for assembling the first object 10 usually have a common size coupling means 1011 and a common size engagement means 1012 regardless of whether or not the three-dimensional shape is the same. Are preferably provided. Alternatively, the engaging means 1011 and the engaging means 1012 having compatibility may be provided.

In the present embodiment, as shown in FIGS. 1A and 1B, the first object 10 has three blocks 101a having a rectangular planar shape and a planar shape having a block 101a. An example will be described in which the block is assembled with two blocks 101b each having a rectangular shape divided into two in a direction perpendicular to the longitudinal direction.

In addition, as the assembly-type toy block 101, a commonly used assembly-type toy block can be used. For example, as the assembly type toy block 101, a block disclosed in Japanese Utility Model Publication No. 37-18847 can be used.

In the present embodiment, the case where the first object 10 is an object assembled with one or more assembling-type toy blocks 101 is described as an example. May be an object other than the object assembled in the block 101. For example, the first object 10 may be an object formed by molding using a mold, injection molding, or the like, or may be an object manufactured by cutting or the like. Further, the first object 10 may be an object made of a material (for example, resin) filled in a cavity portion of a second object, which will be described later, manufactured so as to be hollow. good. The material of the first object 10 does not matter. For example, as the material of the first object 10, resin, metal, wood, or the like can be used. The first object 10 is preferably an object excluding an object produced by 3D printing.

The second object 20 is an object different from the first object 10 and is attached to the first object 10 so as to cover at least a part other than a part of the surface. Covering at least a portion other than a portion of the surface means, for example, covering a surface other than at least a portion of the surface of the first object 10. For example, the second object 20 may be an object attached so as to cover the entire surface of the first object 10. For example, the second object 20 may be an object attached to the first object 10 so as to cover at least a portion other than the bottom surface. For example, the second object 20 may be an object attached so as to cover the entire surface including the bottom surface of the first object 10. The bottom surface of the first object 10 is, for example, the bottom surface of one or more blocks 101 arranged at the lowermost position among the one or more blocks 101 constituting the first object 10. The bottom surface of the first object 10 is, for example, a surface that is the lowermost surface of the first object 10 when the composite object 1 is placed on a plane. The object different from the first object 10 here may be considered to mean that the first object 10 is not an object produced by at least 3D printing, for example.

The surface shape and color of the second object 20 are not limited. For example, the second object 20 may have a surface shape indicated by 3D modeling data of one subject. For example, the second object 20 may have a surface shape indicated by 3D modeling data created using one or more images obtained by photographing one subject from different directions. The 3D modeling data is data that defines, for example, the shape of an object in a virtual three-dimensional space. The 3D modeling data may include information such as the texture and color of the surface of the object, and information such as the material and color of each part of the object. The 3D modeling data may be referred to as 3D data, a 3D model, or the like. Moreover, it is preferable that one or more images used for creation of 3D modeling data are two or more images. The one or more images obtained by photographing one subject from different directions may be one or more still images, and one or more frame images constituting a moving image obtained by photographing one subject from different directions. There may be. Further, the one or more images obtained by photographing here may be images photographed by a 3D scanner or the like. Since a technique for acquiring 3D modeling data having the appearance of an object from one or more images obtained by photographing the object in real space is a known technique, a detailed description thereof is omitted here. For example, refer to the following Patent Document 2 (Patent Document 2: Japanese Patent Laid-Open No. 2001-166809 (first page, FIG. 1, etc.)). The format, file type, etc. of 3D modeling data used here are not limited. The 3D modeling data may be 3D modeling data acquired by tomography such as CT scan.

For example, using the 3D modeling data acquired in this manner, modeling data of one or more parts 201 constituting the second object 20 is created, and the modeling data is used to perform the first 3D printing described later. A part 201 constituting the second object 20 is produced.

The surface shape of the second object 20 may be any surface shape. For example, the surface shape of the second object 20 may be a shape showing the appearance of an animal such as a human, a pet, or a plant, such as an article such as an automobile or an airplane, a house, a castle, a tower, etc. The shape which shows the external appearance of a building may be sufficient. Moreover, the shape which shows the external appearance, a cross section, etc. of an organ etc. may be sufficient. Further, the color of the second object 20 does not matter. For example, the second object 20 may be an object having a color indicated by a material used for printing, may be an object printed with a material colored with two or more colors, and has a uniform surface. It may be an object painted in the above colors.

The shape of the second object 20 is preferably such that when the composite object 1 is placed on a plane, the first object 10 is completely hidden. For example, it is preferable to attach the second object 20 so as to cover at least a portion other than the bottom surface of the first object 10. Further, the second object 20 is preferably made of an opaque material, an opaque coloring, or an opaque coating so that the internal first object 10 cannot be seen. By doing so, the first object 10 can be used as an internal reinforcing material, and in a state where the composite object 1 is placed on a plane, the first object 10 cannot be seen from the outside. The influence of the first object 10 on the appearance of the composite object 1 can be minimized.

The second object 20 is composed of one or more parts 201 produced by 3D printing. For example, it has a shape that covers a part other than the bottom surface of the first object 10 by combining two or more parts 201 constituting the second object 20 such that each of the parts 201 is arranged at a predetermined location. This becomes the second object 20. In this embodiment, as an example, a case where the part 201 constituting the second object 20 is two parts, ie, a first part 201a and a second part 201b will be described as an example.

The part 201 produced by 3D printing is a part 201 produced (for example, printed) using a 3D printer (not shown). The 3D printing method used for manufacturing the component 201 is not limited. For example, as a 3D printing method, for example, an optical modeling method, powder sintering modeling, powder gypsum modeling, a hot-melt lamination method, an inkjet method, and the like are known. The 3D modeling data of each part constituting the second object 20 used for 3D printing may be 3D modeling data prepared in advance, and is created using an image of a subject as described later. 3D modeling data may also be used.

Since each component 201 constituting the second object 20 is manufactured by 3D printing, the material of each component 201 is a material that can be manufactured by a 3D printer. The material that can be produced by the 3D printer is determined by materials such as so-called filaments, toner, ink, and curing liquid used by the 3D printer. For example, in 3D printing, a part made of a material such as resin or metal can be printed. Therefore, the material of the manufactured part 201 is, for example, resin or metal.

When the second object 20 is composed of a plurality of parts 201, the plurality of parts 201 constituting the second object 20 are each fitted with one or more fitting structures that are fitted to the adjacent parts 201. 2012 may be provided. For example, the fitting structure 2012 is provided in each of the contact parts of the two adjacent parts 201, for example, the contact surface when a plurality of parts 201 constituting the second object 20 are combined. The fitting structure 2012 is opposed to, for example, a protrusion (not shown) or a protrusion provided on one component 201 and a protrusion or recess of one component adjacent to the one component. It is comprised with the recessed part (not shown) fitted in this protrusion part and convex part provided in the position to do. For example, in FIG. 1B, a projection 2012a provided in the first component 201a and a recess 2012b provided in the second component 201b and fitted into the projection 2012a are fitted into the fitting structure 2012. Is configured.

It is preferable that the second object 20 has a shape that fits to the first object 10. For example, each of the two or more parts 201 constituting the second object 20 has a concave portion 202 (hereinafter referred to as a fitting concave portion) having a shape fitted to the first object 10 on the inside. In addition, by combining the parts 201 to form the second object 20, the fitting recess 202 of each part 201 is also combined, and the portion where the fitting recess 202 is combined becomes the first object 10. It becomes a shape which fits. In addition, when the second object 20 is configured by one component 201, the fitting recess 202 is provided, for example, so that the bottom surface opens with respect to the one component 201 that configures the second object 20. It becomes a recessed part fitted to one object 10. The fitting recess 202 preferably has a shape that fits with the coupling means 1011 included in the first object 10 fitted into the fitting recess 202. The fitting recess 202 may have, for example, one or more recesses 2021 or grooves (not shown) that fit into one or more protrusions that are the coupling means 1011 located on the surface of the first object 10. .

FIG. 3 is a flowchart showing a method for manufacturing the composite object 1.

FIG. 4 is a diagram (FIGS. 4A and 4B) for explaining a method of manufacturing the composite object 1. FIG.

FIG. 5 is a display example (FIGS. 5A and 5B) for explaining the method of manufacturing the composite object 1. FIG.

FIG. 6 is a display example (FIGS. 6A and 6B) for explaining a method of manufacturing the composite object 1. FIG.

FIG. 5A, FIG. 5B, FIG. 6A, and FIG. 6B show 3D modeling displayed on a monitor such as a computer that executes software for creating 3D modeling data, for example. It is a display example of data.

Next, an example of a method for manufacturing the composite object 1 will be described with reference to the flowchart of FIG. 3 and the display examples of FIGS. Here, the case where the composite object 1 as shown in FIG. 1 is produced will be described as an example.

(Step S101) The user acquires one or more images obtained by photographing one subject. For example, the user captures one subject from two or more different directions using an imaging device such as a camera, and acquires two or more photograph images. For example, as shown in FIG. 4A, a single subject 40 is photographed by a camera 41 from a plurality of directions, and a plurality of images 42-44 as shown in FIG. 4B are acquired.

(Step S102) Using the image acquired in step S101, the computer executes software or the like for creating 3D modeling data from the image, and acquires 3D modeling data indicating the surface shape of the composite object 1. This data may be considered as data defining the surface boundary of the composite object 1. For example, it is assumed that 3D modeling data 51 as shown in FIG. This 3D modeling data is assumed to be placed on one virtual plane, for example. Note that the output size of the 3D modeling data may be set by the user, or may be set by default. Further, this output size may be changed as appropriate in the 3D modeling data according to a user instruction or the like.

(Step S103) The 3D modeling data of one or more blocks 101 is arranged inside the 3D modeling data acquired in Step S102. The arrangement of the 3D modeling data in the block 101 is performed by a user or the like using, for example, a computer that executes software or the like for creating 3D modeling data. The same applies to the following steps S104 to S108. For example, the 3D modeling data of the block 101 is arranged inside the 3D modeling data acquired in step S102 in accordance with an operation performed by the user on an input device (not shown).

When the 3D modeling data of the block 101 is stacked, for example, a part corresponding to one or more combining units 1011 of the 3D modeling data of one block 101 is an engaging unit 1012 of the 3D modeling data of the block 101 to be stacked. It is made to engage with the part corresponding to. In addition, it is preferable that all of the 3D modeling data of the two or more blocks 101 arranged in the 3D modeling data acquired in step S102 are connected by the combining unit 1011 or the like. Data composed of 3D modeling data of one or more blocks arranged in this way may be considered as modeling data for setting the structure of the first object 10 and becomes an internal structure of the composite object 1. It may be considered as data defining the structure of the first object 10.

When stacking the 3D modeling data of the block 101, for example, it is preferable that the surface boundary of the 3D modeling data of any block 101 does not protrude from the surface boundary of the 3D modeling data acquired in step S102. However, you may arrange | position so that the bottom face of 3D modeling data of the one or more blocks 101 arrange | positioned at the lowest part may correspond with the bottom face of 3D modeling data acquired by step S102. By doing in this way, in step S109 mentioned below, a plurality of parts which constitute the 2nd object 20 arranged so that at least the bottom of the 1st object 10 may be covered can be acquired by 3D printing.

Here, for example, as shown in FIG. 5B, three 3D modeling data 52a respectively corresponding to the three blocks 101a and two 3D modeling data 52b respectively corresponding to the two blocks 101b are arranged. Suppose that A combination of the 3D modeling data 52 a and the 3D modeling data 52 b is the 3D modeling data of the first object 10.

In addition, since the 3D modeling data which shows the block for toys is piled up, combining 3D modeling data using a connection means like a block, since it is a well-known technique, detailed description is here. For example, refer to the following URL (http://ldd.lego.com/ja-jp/).

(Step S104) 3D modeling data indicating a difference between the 3D modeling data acquired in step S102 and the 3D modeling data of the first object 10 acquired in step S103 is acquired. For example, the 3D modeling data of the first object 10 acquired in step S103 is subtracted from the 3D modeling data acquired in step S102. That is, the 3D modeling data 52a and the 3D modeling data 52b are subtracted. The difference 3D modeling data acquired in this way is 3D modeling data 53 for setting the structure of the second object 20. The 3D modeling data 53 may be considered as data that defines the structure of the second object 20 that is the external structure of the composite object 1. The difference may be acquired, for example, according to an instruction or the like to the user, or may be acquired automatically. The portion where the 3D modeling data 52a and the 3D modeling data 52b are arranged becomes a portion 55 corresponding to the fitting recess.

(Step S105) The 3D modeling data 53 for the second object 20 acquired in Step S104 is divided into two or more 3D modeling data. For example, the 3D modeling data 53 is divided into a plurality of parts at a position designated by the user. For example, as shown in FIG. 6A, it is assumed that 3D modeling data 53 indicating a difference is vertically divided into two. In the figure, a line 54 is a line indicating a division position. In addition, when it is not necessary to divide the second object 20 into a plurality of parts 201, this process may be omitted. The division may be performed, for example, by a surface designated by the user.

(Step S106) A fitting structure 2012 is provided in the divided portion of the 3D modeling data divided in Step S105. For example, the shape of the protrusion 2012a prepared in advance is provided on one divided surface of the two divided parts 201, and the protrusion is formed on the other divided surface at a position facing the protrusion 2012a. A shape of a recess 2012b prepared in advance to be fitted into the portion 2012a is provided. The position where the fitting structure 2012 is provided is specified by the user using an input device (not shown), for example. For example, as shown in FIG. 6B, a fitting structure 2012 is provided at the divided position.

(Step S107) In step S106, 3D modeling data of each component 201 provided with the fitting structure is output. The output here may be, for example, transmission to a 3D printer (not shown) or writing of data to a recording medium (not shown).

(Step S108) Information specifying each block 101 indicated by the 3D modeling data of the block 101 arranged in Step S103 by a computer or the like that executes software or the like for creating 3D modeling data, and each block 101 indicated by this information Outputs information indicating the position to be placed. The information specifying the block 101 may be an identifier such as a block model number, information indicating a block type, or information indicating a block size or shape. Moreover, the information which shows the position where each component 201 which provided the fitting structure in step S106 is arrange | positioned is output. The information output here may be considered as information indicating how to assemble or combine the composite object 1 to the user, for example, information indicating an assembling method. The information indicating the position here may be information indicating a relative positional relationship between the blocks 101, between the components 201, or between the block 101 and the components 201. As information indicating the position where the block 101 or the part 201 is arranged, for example, the 3D modeling data of one or more blocks 101 arranged in step S103 or the 3D modeling data of each part 201 obtained in step S106 is used as a wire frame. You may output the image rendered by. If the size of the block to be used can be specified from the image to be output, the information specifying the block 101 may not be output.

The information indicating the position where each block 101 is arranged and the information indicating the position where each component 201 is arranged are, for example, the 3D modeling data of the block 101 arranged in step S103 or each part acquired in step S106. This is information created by the user using the 3D modeling data 201.

(Step S109) Using a 3D printer (not shown), each component 201 is 3D printed by a 3D printer (not shown) using the 3D modeling data of each component 201 output in step S107. Thereby, a component 201a and a component 201b as shown in FIG. 1B are obtained.
When the 3D modeling data of block 101 is stacked in step S103, make sure that at least a part of the surface boundary of the 3D modeling data of block 101 does not protrude from the surface boundary of the 3D modeling data acquired in step S102. Also good. Then, 3D printing may be performed using the 3D modeling data of each part thus obtained. By doing in this way, the several components which comprise the 2nd object 20 arrange | positioned so that at least a part of surface of the 1st object 10 may be covered can be acquired by 3D printing.

(Step S110) Referring to the information acquired in Step S108, one or more blocks 101 indicated by this information are obtained, and the obtained blocks 101 are stacked to form a first object 10 as shown in FIG. Is made. Furthermore, referring to the information acquired in step S108, the component 201 obtained in step S109 is attached to the first object 10. When the component 201 is attached to the first object 10, the concave portion 2021 in the fitting concave portion 202 of the component 201 provided at a position facing one or more coupling means 1011 of the first object 10 is opposed to the one. The above coupling means 1011 is fitted. In addition, when the 2nd object 20 is comprised with several components 201, after forming the 2nd object 20 by combining all the components 201 so that the fitting structure 2012 may fit, the 1st object 10 is formed. The second object may be attached to the second object, and in this case, it may be considered that the part 201 is attached to the first object 10. When the blocks 101 are stacked, the blocks 101 may be bonded using an adhesive or the like. Moreover, you may make it adhere | attach between the components 201 which comprise the 2nd object 20, or between this component 201 and the 1st object 10 using an adhesive agent. Thereby, the composite object 1 as shown to Fig.1 (a) is produced.

Note that the user who outputs the 3D modeling data output in step S107 and the user who performs 3D printing or the like in step S109 may be different users.

As described above, according to the present embodiment, it is possible to provide a composite object that can be manufactured with high quality and low cost by using 3D printing.
